Jadever 70mm Aluminum Alloy 90-Degree Corner Clamp (70mm Max Jaw Capacity, 35mm Jaw Depth, Swing-Jaw Alignment, Die-Cast Aluminum Frame, Single-Handle Steel Screw Drive)
Eliminate crooked picture frames, out-of-square cabinet boxes, and slipping miter joints when gluing, screwing, or welding raw materials together. The Jadever JDACC1528 Corner Clamp replaces awkward C-clamps and manual hand-holding that cause joint shifting mid-assembly. By combining a rigid, die-cast aluminum frame with an oscillating swing-jaw pivot and a solid steel threaded shaft, this 90-degree corner clamp locks structural joints at a true 90-degree right angle—giving woodworkers, cabinetmakers, and DIYers a gap-free alignment system.
Die-Cast Aluminum Frame & 70mm Clamping Capacity
Heavy-Duty Die-Cast Aluminum Alloy Chassis: Cast from lightweight, high-tensile aluminum alloy. This rigid structural frame completely eliminates flex under high clamping pressure while remaining resistant to weld spatter, rust, and workshop impacts.
70mm ($2.75\text{ Inch}$) Maximum Jaw Opening: Features a generous 70mm clamping span, accommodating thick hardwood lumber, structural square tubing, metal flat bars, picture frame moldings, and glass sheets.
35mm ($1.37\text{ Inch}$) Deep Jaw Profile: Built with 35mm tall clamping walls that provide ample surface contact area to hold tall boards upright without twisting or lifting during joint assembly.
Self-Adjusting Swing Jaw & Steel Threaded Drive
Self-Adjusting Swing-Jaw Pivot: Outfitted with an oscillating jaw block that swivels smoothly on a center pin. This floating jaw design automatically adjusts to clamp two workpieces of equal or differing thicknesses simultaneously without forcing the joint out of square.
Heavy-Duty Steel Threaded Screw & Ergonomic Grip: Driven by a cold-rolled steel acme thread screw fitted with an ergonomic, high-torque handle. The smooth-rolling thread applies intense, controlled clamping force with minimal hand effort.
T-Joint & Corner Joint Access Openings: The corner apex features open clearance slots, allowing wood screws, pocket-hole drivers, dowel jigs, or welding torches to access the joint line cleanly while the clamp remains fully locked.

Best Use Cases
Cabinetmaking & Box Frame Assembly: The absolute daily baseline tool for carpenters and cabinetmakers in Salem to clamp cabinet carcases, drawer boxes, shelving units, and furniture frames perfectly square before driving screws or pocket-hole fasteners.
Picture Framing & Miter Joint Glue-Ups: Perfect for picture framers and woodworkers to apply even glue pressure across 45-degree mitered corners without the joint slipping or splitting under load.
Light Metal Fabrication & Square Tube Welding: Ideal for metal fabricators to position steel square tubing, angle irons, or flat bars at exact 90-degree angles for tack welding without requiring secondary angle checks.
Glass Panel & Shelf Installation: An indispensable alignment tool for glass fitters to securely position glass panels or acrylic display dividers at right angles during silicone curing.
TK Pro Tip: A 90-degree corner clamp is a high-precision squaring tool, and dry-fitting your joint before applying glue is the key to achieving gap-free corners! Before applying wood glue or driving fasteners, always clamp your raw workpieces dry in the JDACC1528 to verify that your miter or butt cuts meet flush with zero light gaps. Thanks to the swing-jaw design, you can clamp two boards of different thicknesses—such as a 1/2″ drawer side to a 3/4″ drawer front—and the jaw will pivot automatically to lock both pieces down tightly. When using the clamp on softwoods or finished hardwood surfaces, place small scraps of thin cardboard or wooden shims between the aluminum jaws and your workpiece to prevent jaw pressure marks!
The TK Tools Promise
Verified: 100% original, factory-authentic Jadever workshop equipment—sourced directly and verified for genuine die-cast aluminum alloy construction, true 70mm clamping capacity, and 35mm jaw depth parameters.
90-Degree Squareness & Thread Smoothness Bench Check: Because structural woodworking and framing leave zero margin for out-of-square joints, our technical team in Salem manually unboxes sample units, verifies the exact 90-degree internal angle using precision machinist squares, tests the smooth travel of the steel lead screw, and checks the swing-jaw pivot action before approving the color box pack for final warehouse dispatch.
Fast Delivery: Packed securely inside custom shock-absorbent multi-layer cushioning and shipped rapidly from our main central hub straight to your garage counter, industrial shop, or field tool chest.
